Specification of-Letters Patent.

Application filed April 22, 1911. Serial No. 622,664.

To all whom it may concern:

Be it known that I, JOHN WALDHEIM, citizen of the United States, andresident of Newark, in the county of Essex and State of New Jersey, haveinvented certain. new and useful Improvements in Type-VVriting Machines,of which the following is a specification.

My invention relates to ribbon mechanism for typewriting machines andits general object is to provide improved mechanism of the characterspecified and more especially to provide devices which positivelycontrol the vibratory movements of the ribbon so as to prevent overthrowof the ribbon at printing operation.

In the present instance I have accomplished the result sought byincluding tog gle devices in the train of ribbon vibrating mechanism,the toggle being normally broken and operating, when straightened, atprinting operation to raise the ribbon so that it is presented properlyto the types.

Means are also provided for varying the toggle devices and the normalsetting of the toggle devices so that the toggle may oper-" ate toposition and control the ribbon for a plurality of ribbon fields.

The form of my invention herein shown is adapted to theB-emington No. 10type writing machine but the principles of the invention may be readilyapplied to other styles of writing machines. L.

To the above and other ends .my invention consists in the features ofconstruction, combinations of devices and arrangements of partshereinafter described and particularly pointed out in the claims.

In the drawings, Figure 1 is a fragmentary vertical front to rearsectional view of a No. 10 Remington typewriting machine embodying myinvention. Fig. 2 is a fragmentary side elevation partly in sectionshowing parts of the ribbon mechamsm in different relationships fromthose in which they appear in Fig. 1. Fig. 8 is a'rear ele- .vationpartly in section corresponding to Fig. 2.. Figs. 4 and 5 are operatingviews of the ribbon mechanism showing the parts set for using the lowerribbon field. Figs.

' 6 and 7 are perspective views of parts of the ribbon mechanism.

As shown in Fig. 1 the main frame of the machine comprises a base 1,corner posts 2 and a top plate 3 which supports fixed track Ways 4 for aplaten carriage comprising a truck 5 connected through anti-frictionballs 6 with said track ways. The truck is connected by links 7 with ashiftable platen frame 8 in which is mounted a cylindrical platen 9. 10which cotiperates with a shift rail 11 secured at the top of a shiftableframe comprising uprights 12, a cross bar 13 and downwardly extendingarms 14 pivotally connected at their lower ends at '15 to shift keylevers 16. .The letter space feed moveeach provided with a restoringspring 25.

Each key lever is connected by devices comprising a link 26, a lever 27and a second link 28 with a type bar 29 supported'on a hanger 30 securedto a segment 31, the type bars, when actuated, cooperating with thefrontface of the platen 9L A ribbon 32 which, in the present instance,,is divided into longitudinal fields a and b of differentcharacteristics, is wound upon ribbon spools, one ofwhich 32 is shown,the ribbon spools being arranged below the top plate one at each side ofthe machine and being adapted to be alternately connected .by mechanismof known character (not herein shown) with the carriage, during leftwardmovements thereof, so as to feed the ribbon longitudinally buck andforth in opposite direc tions, The ribbon is led up from the spools overfixed guides and directed inward and rearward toward the platen, beingthreaded centrally of the machine through a vibratory ribbon carrier orvibrator which, as shown in Fig. 6, comprises an upper portion or body33 provided with ribbon guiding slots 34L and a type opening 35. The

vibrator is provided with a rearward ofi'- set 36 and from the offsetportion depends a stem 37 having a guide slot 38. The upper part of thestem is provided with cars 39 which coil around and pivotally engage across pin 40 carried at the forward ends of arms 41 of a lever member,which'further Patented May '7, 1912.

On the platen frame 8 is a roller jecting end portions.

' which further includes a body portion 46,

the upper end whereof, as appears from Figs. 2 and 3, is forwardlyinclined and is secured by screws 47 to the shift rail 11. A screwst8likewise secures the bracket 46 to the cross bar 13 of the shift frame.The

bracket has a lateral. extension 49 which is also secured to the crossbar by a screw 50 and terminates in a downward extension 51 having arearwardly bent car 52. The bracket further comprises a downwardextension 53 having a. rearwardly bent por tion 5 1.

The arm 4-2 of the lever member has a rearward and downward extension 55which is pivotally connected at 56 with a depending toggle member 57,the lower end of which is pivotally connected at 58 with a second togglemember 59, the lower end whereof carries a cross pin 60 having pro- Asshown in Fig. 1 the pivotal connection or pin 58 is engaged by a slot 61at the upper end of a lever 62 which is fulcrumed on a screw pin 63mounted on the bracket portion 54-. Normally the lever 62 is positionedagainst a limiting stop 64 as shown in Fig. 1 by a coiled spring 65, oneend of which is connected to the upper end of the lever 62 and the otherend to an car 15* on the left-hand ear 45. The toggle comprising themembers 57 and 59 is normally maintained broken as in Fig. 1 by a coiledspring 66 which is connected at its front end to the toggle member 59and at the rear end to the lever 62. In the position shown in Figs. 1and 2 the cross pin 60 is maintained in a notch or slot 67 on the frontedge of the leverv62. The lower arm of said lever is connected by a link68 with an upright crank arm 69 secured to the rock shaft 19.. Theconstruction is such that when the universal bar is actuated by one ofthe printing keys it swings the crank arm 69 rearward, operating throughthe link 68 to vibrate the lever 62, the upper arm whereof SWlIlgSforward and operates to straighten thetoggle57, 59 as shown in Fig. 2.The straighten ng of the toggle swings up the operating lever 41--43which moves upward in a slot or opening 46 in the bracket 16 and therebyraises the vibrator so as to present the upper ribbon field a to thetypes as will be understood from Fig. 2 wherein the printing point isindicated by the dotted line 7). The vibrator is guided during its vib'atory movements by a grooved pin 70 secured to a plate 71 fixed by ascrew 72 to the shift bar 13. It will be observed that during themovement from Fig. 1- to Fig. 2 the toggle member 59 is rigid on' thelever 62. being controlled by the pins 58 and 60 which are maintainedseated in the slots 61 and 67, respcctively. In effect then the toggle,during the movement from normal position as shown in Fig. 1 to theprinting position for the upper field (2 as shown in Fig. 2, may be saidto comprise the member 57 and the member 62, the two members beingpivotally connected at 58 and the member 62 hav- "ing a fixed pivot 63.

In order to use-the lower ribbon field 7) means are provided forchanging the normal setting of the toggle member 59 and providing saidmember with a stationary support independent of the lever 63. Said meanscomprises a member 72 which is shown clearly in Fig. 7. Said memberincludes parallel side arms 73 and 74 joined by a cross bar 75. Each armis formed with an inclined or cam edge 76 and a seat or depression 77,which are adapted to cooperate with the end portions of the cross pin60, the member 72 being positioned to underlie the cross pin 60. Thelower end of the arm 7 1 is provided with a hub 7 8 which is secured tothe inner end of a rock shaft 79. Said rock shaft, as clearly appearsfrom Fig. 3, bears in the ears 52 and 54 on the bracket 46 and extendsleftward, terminating in a finger button 80 by which the rock shaft andthe member 7 2 may be manually turned.

Detent devices are provided for maintaining the rock shaft and themember 72 in either of two set positions. Said detent de vices comprisean arm 81 having a hub 82 which is fixed to the rock shaft 7 9 (Figs. 2and 3).' The outer end of the arm 81 is formed with notches 83 and 84with which cooperates a U-shaped spring detent 85 secured by screws 86to the oracket portion 49. \Vhen the detent 85 is engaged with the notch84 as shown in Fig. 2 the member 72 will be maintained in inoperativeposition as shown in Figs. '1 and 2. By turning the rock shaft 79forward until the spring detent 85 engages with the notch 83, as shownin Fig. 4, the cam edges 76 are caused to contact with the pin 60,forcing the lower end of the member 59 forward and ll])\:l1.(l until itcontacts with limiting stops 87 formed by rearwardly bent ears on thebracket 16. At the arresting moment the cross pin 60 will be seated inthe notches or depressions 77 which form a bearing for said cross pinand consequently for the lower toggle member 59, which, it will beobserved, has. by the above described operation, beenraised to a newnormal position and provided with a support or pivot independent of thelever 62. The resetting of the toggle member 59 does not atfect theupper toggle member 57 and consequently the normal position of thevibrator and the operating lever is not altered by the resettingoperation.

H, with the parts set as in Fig. 4:, one of the printing key levers beactuated, the toggle comprising the members 57 and 59 will bestraightened by the action of the upper end of the lever 62 on the pivotpin 58. The straightening of the toggle, as shown in Fig. 5, willoperate to elevate the operating lever or member and the vibrator. Theupward movementof the vibrator will be .of a greater extent than thatdescribed in connection with Figs. 1 and 2 and will be suiiicient topresent the lower ribbon field b to the types as shown in Fig. 5. On thereturn movement the parts will be restoredtonornial positionby thevarious restoring dc vlces comprising the springs 65 and 66. It

will be apparent that for both extents of ,throvvthe vibrator will be socontrolled by and the actuating and controlling devices thereforcomprising the operating lever member and the toggle devices down to andincluding the lever 62 are all mounted and supported on brackets whichare carried by the platen shifting frame platen is shifted the vibratorand the actuat-- ing and controlling devices aforesaid. are shifted withit and maintain the same relationship subsequent to the shift as priorthereto. During such shifting movements the link 68 will swing upwardabout its connection with the crank arm 69 as a center.

I t will be observed that by my present. invention I provide ribbonvibrating mechanism for typewriting machines, which vibrating mechanismcomprises a toggle; that in the present instance said mechanism includesa ribbon vibrator and an operating lever and that the toggle is directlyconnected to the operating lever; that in a frontstrike typewritingmachine I combine with a vertically disposed ribbon vibrator, ahorizontally disposed operating lever or member with which said vibratoris connected, and a toggle, one element whereof is connected to theoperating lever between its fulcrum and the vibrator, said toggle beingnormally broken and becoming sub stantially, vertically disposed whenstraightened by the operation of one of the printing keys; that ribbonfield changing mechanism is provided which comprises toggle devices,said toggle devices being variable, the variation being efiiected bymanually controlled so that when the ages and means for at means andresulting in a variation in the printing field of the ribbon or in thewidth wise portion of the ribbon presented to the types; that means areprovided for throws mg into and out of operation certain of the toggledevices to vary the printing field of the ribbon; that in the presentinstance the device which is thrown out of and into operation is thelower toggle arm, element or member 59 which at times is moved bodilywith the lever 62 and at other times is operated or swung piv'o-tallyabout a fixed support by said lever 62; that the toggle has a movablepivot at the top of its upper arm and, that the lower arm'of the togglemay be changed from one element, 62, element, 59, and thereby the fixedpivot or anchorage at the lower end of the toggle may be changed orraised and the length of the lower toggle arm altered, or decreased inlength and vice versa; that in combination with a ribbon vibrator thereis provided a toggle, an actuating device for the toggle: and means forrendering the actuating device part of the toggle, that said actuatingdevice is in the present instance the lever 62; and that a handcontrolled shifter is provided for throwing the arm59 into and out ofoperation as a toggle member, said 'SlllftGI operating as a support forsaid toggle member when it ,is operating as such independently ofitsiformer support, 62, the construction roviding toggle devices havinga plurality of anchorages and means for at will changing from oneanchorage to another.

The principles of my invention may be adapted in whole or in part toother construct-ions besides the one illustrated and described hereinand various changes may be made in the described construction,withoutdeparting from the spirit and scope of my said invention.
